10 May 2013 AUTO ENHANCEMENT FOR IMAGES AUTO ENHANCEMENT FOR IMAGES to make better- looking images. Author: Divakar Roy

Shankar -
With heuristic I basically meant, from my experiments those values seemed to give me the "best" results. Again the "best" here is subjective to some extent. There is no other material involved.

As said earlier, those are heuristic thresholds and nothing to do with them being positive or negative.

Those are just heuristic thresholds.
02 Feb 2013 GINPUT on GUI (Keeping toolbar features on) & Use of custom pointers GUI Framework to use GINPUT (keeping all toolbar features on) + Custom pointers for plots and more. Author: Divakar Roy

Harold -

Maybe you can start with my GUI and add your GUI stuffs on top of it.

Otherwise if you want to add my GUI stuffs on top of yours, you need to make the changes listed below and it is assumed that you are starting off with a blank GUI that automatically creates functions like OpeningFcn, etc. on your behalf.
Changes:
1. Edit these two functions to include my stuffs from – OpeningFcn and OutputFcn.
2. Add these functions that are needed for OutputFcn - detect_mouse_hover, detect_mouse_press_print_plus, detect_mouse_press_do_nothing, estimate_new_position. The toolbar functions can be similarly edited, if needed.

Hope this helps!

Nicolas,

Yes, that should be possible. You are needed to trigger an infinite loop inside function - detect_mouse_press_print_plus or make a new one similar to it but with an infinite loop that plots the marking symbols ('+' in the code) continuously.

Then add WindowButtonUpFcn in the function - detect_mouse_hover, so that the infinite loop could be broken when user releases the pressed mouse button.

To accomplish all this, you most probably would require a flag.

Hope this helps.

what would happen if those threshold levels are changed and generally we use positive threshold levels but here u used negative thresholds. what is the use of negative threshold levels here.
